Titan Usa TC29231 Drill Bit No 31 0.1200 in Solid Carbide

Product Description

The TITAN USA TC29231 is a screw machine length drill bit engineered for precision drilling in tight spaces and short-stroke applications. Built from solid carbide and coated with AlTiN (aluminum titanium nitride), it handles hardened steels, stainless, cast iron, and high-temp alloys where high-speed steel tooling falls short. The 135-degree split point geometry reduces thrust force, self-centers on entry, and minimizes walking without a center punch. At 2 inches overall length, this stub-length bit fits standard drill chucks and CNC tool holders where a jobber-length bit would be impractical. It cuts right-hand with a regular spiral flute and a straight shank sized for wire gauge No. 31 (0.1200 inches).

Screw machine length drill bits like the TC29231 are used in production machining, CNC drilling centers, manual drill presses, and bench-top operations where rigidity and chip evacuation matter more than reach. The stub-length body reduces deflection, making it well suited for tight-tolerance holes in metal fabrication, automotive, aerospace component work, and general machine shop use. The AlTiN coating extends tool life in dry or minimally lubricated cutting conditions and maintains hardness at elevated cutting temperatures.

Key Features

• Solid carbide construction for superior hardness and wear resistance in ferrous and non-ferrous metals
• AlTiN coating resists heat buildup and extends tool life in dry or semi-dry cutting
• 135-degree split point self-centers on the workpiece and reduces required feed force
• Screw machine (stub) length of 2 inches overall reduces deflection and improves rigidity
• Regular spiral flute with 0.75-inch flute length promotes consistent chip evacuation
• Right-hand cut, straight shank compatible with standard drill chucks and CNC collets

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide drill bit for any drill press, CNC machining center, or hand drill with a chuck or collet sized for a straight-shank tool at 0.1200-inch (No. 31 wire gauge) diameter.

Installation Notes

This bit is intended for installation by machinists, toolroom technicians, or experienced CNC operators. Always power down and lock out the spindle drive before changing tooling. Seat the straight shank fully and evenly in the chuck or collet before tightening to manufacturer-specified chuck torque. Carbide is brittle — avoid lateral loading, impact contact with hard surfaces, and interrupted cuts without appropriate feed rate reduction.
